Data, passed from ModalPage to ModalWindow, is not accessible in
WindowClosedCallback
-------------------------------------------------------------------------------------
Key: WICKET-3808
URL: https://issues.apache.org/jira/browse/WICKET-3808
Project: Wicket
Issue Type: Bug
Components: wicket-core, wicket-extensions
Affects Versions: 1.5-RC4
Environment: Win 7, FF
Reporter: Mishelle Bonq
Priority: Critical
Because of changes of pages processing an unacceptable behavior was detected.
During such a processing in case if we try to pass some data from page on
opened modal window to a modal window (which is an element of background page).
The quickstart project was made to show this wrong behavior.
Steps to reproduce:
1. Run quickstart project. Open HomePage. You'll see a link "Show ModalWindow".
Click it. As an action on this click a new PageCreator is set for ModalWindow,
which creates a new instance of ModalPage & pass a callback to this instance.
Inside the callback the visibility of hidden element from HomePage is changed
(The text "Hello, World!" became visible).
2. So, a ModalWindow will be shown with a ModalPage as content. In ModalPage
you'll see another link "Close ModalWindow and show hidden text on HomePage".
Click this link.
This click must leads to setting the callback (which we've already passed in
step 1 to ModalPage instance) to ModalWindow & close this ModalWindow.
Closing ModalWindow happens in a correct way. But we don't see the hidden text.
The reason of this behavior is: when we set the callback from ModalPage to
ModalWindow (element of HomePage) the numericId of HomePage is changed and this
page is serialized with another id. During ModalWindow closing
WindowClosedCallback is called. In this WindowClosedCallback we are trying to
call our callback, which had to be set from ModalPage. But script, which
handles WindowClosedCallback from browser, references to a HomePage with old
numericId & of cource without set callback.
